Re: jndi question
brian, would you mind giving me a list of the applicable jar files you have in your web-inf/lib folder? i removed the files below, and made sure the files naming-factory and naming resources were in my common/lib folder. now i'm getting this stack exception: javax.servlet.ServletException: Cannot create resource instance org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:848) org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:781) org.apache.jsp.test_jsp._jspService(org.apache.jsp.test_jsp:69) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:322) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:291) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) *root cause* javax.naming.NamingException: Cannot create resource instance org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.java:132) javax.naming.spi.NamingManager.getObjectInstance(NamingManager.java:304) org.apache.naming.NamingContext.lookup(NamingContext.java:792) org.apache.naming.NamingContext.lookup(NamingContext.java:139) org.apache.naming.NamingContext.lookup(NamingContext.java:780) org.apache.naming.NamingContext.lookup(NamingContext.java:152) com.transcriptionportal.utils.DBManager.init(DBManager.java:34) org.apache.jsp.test_jsp._jspService(org.apache.jsp.test_jsp:53) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:322) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:291) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) Different error this time, so i think i'm getting closer. ;) thanks again. sean Brian Cook wrote: Sean, I copied your code on top of mine and ran it with no problems.

But the only way to configure it is to define the JNDI resources in the web.xml and context.xml files.Technically you should be able to use the globally defined JNDI resources in server.xml, and I have seen configuration set ups doing it when googling. But could never get them to work. This highlights another area of seemingly unneeded complication in Java/Unix development. Using JNDI for data sources which was supposed to help you save time requires that you redundantly define the JNDI resource in at lest 2 if not 3 places. The admin tool which was also supposed to help save time defines the JNDI resources in server.xml which does not really seem to be all that helpful. I am sure there is likely a reason for this but I am ignorant of it. The admin tool is also supposed to let you define JNDI resources per context but it errors out when ever I have tried it. My experience with the Tomcat Admin and Manager tools is that they are worthless. Of the few steps they try to help with more ofte

Re: jndi question
The first post on this included the server.xml, and further down in the page is the relevant part of web.xml ( i just double checked that ). as for context.xml, i have listed it in my webapp.xml file, as well as server.xml as all other examples have suggested. i then tried it in the admin module, where it then put it in server.xml for me. i'm willing to try anything at this point, though, if you have any suggestions. as for my post not being jndi specific, i applogize if that's the case. i'm not really familiar with jndibut when I did a search for 'connection pooling', jndi seemed to be what everyone suggested i use. what i want to do, if it's not clear, is to create a connection pool to my MySql database. thanks, sean Brian Cook wrote: Actually the files I listed are NOT in the first post. It shows the server.xml and the code calling it but does not show web.xml or context.xml. The error you are getting just means that that the JNDI resource being called in the code is not defined in both web.xml and context.xml. In looking at the code snip it in the first post I am not following what you are trying to do. The post is for a JNDI question but in the code it looks like you are calling the DB URL directly. The whole point of JDNI being to get specific URL, and configuration info outside of the code base. I am not following what it is you are trying to do here.
